Arm Intervention/treatment
Experimental: Single Arm
SingleArm: TAF 25 mg
Drug: Tenofovir Alafenamide
subjects switching from Entecavir to single arm TAF 25mg
Other Name: TAF

Primary Outcome Measures :
  1. Results of viral Hepatitis B DNA to be <20 IU/mL [ Time Frame: 48 weeks ]
    The proportion of subjects with plasma HBV DNA levels below 20 IU/mL at week 48.

Secondary Outcome Measures :
  1. Complete viral suppression at study completion [ Time Frame: 96 Weeks ]
    The proportion of subjects with complete viral suppression, i.e., plasma HBV DNA level below 20 IU/mL at Week 96.

  2. Positive eGFR changes at study completion compared to Baseline visit [ Time Frame: 96 weeks ]
    Change in eGFR from baseline to Week 96

  3. Improved Bone Mass Density at study completion [ Time Frame: 96 weeks ]
    % change from baseline in BMD at the hip and lumbar spine at Week 96.
